Knema luteola is one of the few species of Knema, besides K rubens (Sumatra, Peninsular Malaysia) and K. oblongifolia (Peninsular Malaysia), with the twigs in the apical part ± flattened. Knema rubens differs in its longer and thicker indumentum of twig apices, reddish in colour, hairs remaining on the lower side of the midrib, and coarser venation of the leaves, with aréoles more than 0.5 mm diameter; K. oblongifolia has differently shaped male buds. Stout sterile or fruiting specimens may resemble K ashtonii var. ashtonii, which obviously is related, but differs in its larger fruits. The fruits of K. luteola resemble those of K kostermansiana, which are generally larger (longer) and fusiform.
